Our common products we produce routinely are various assemblies of ceramic to metal seals for virtually all the applications including medical, aerospace/military and oil/gas field applications. There are three different types of our products in terms of the purpose of the use and they are (1) a structural seal or joint of ceramic and metal combinations, (2) the second one is an electrical feed through and (3) the third one is an optical window assembly (sometime it is called electro-optical or opto-electronic component). Majority of them have hermetic seal requirement along with few others such as vacuum or specific environment, pressure differentials along with thermal excursions or cryogenic.
